Chrysler Front Wheel Drive Cars 4-CYL 1981-1995 Repair Information

Ignition Module



See Figure 1

The ignition module, referred to as either the Spark Control Computer (SCC) or Power Module by Chrysler, is mounted on the inner, left-hand fender, next to the battery. The SCC or Power Module is what develops into Chrysler's Powertrain Control Module (PCM).

  1. To gain access to the SCC, remove the battery from the vehicle.
  3. Disconnect the air inlet hose from the rear end of the SCC. Position the hose aside without disconnecting it from the air cleaner assembly.
  5. Detach the 10-way and the 14-way engine wiring harness connectors from the SCC.

Do not remove the grease from the 10-way dual connector or connector cavity in the SCC-this grease is used to prevent moisture from corroding the connector terminals.

  1. If the SCC is equipped with a vacuum transducer (carbureted engines), label and disconnect the vacuum hose from the SCC.
  3. Remove the SCC mounting screws and pull the SCC away from the inner fender. Remove the SCC from the vehicle.

To install:
  1. Hold the SCC in position against the inner fender, then install the mounting screws until snug.
  3. If equipped, attach the vacuum hose to the vacuum transducer.
  5. Inspect the amount of grease in the 10-way and 14-way connectors. If there is not at least 1 / 8 in. (3mm) of grease on the bottom of the SCC connector, apply Mopar® Multi-purpose grease Part No. 4318063, or equivalent, over the entire end of the connector plugs before reattaching them.
  7. Push the 14-way and 10-way connectors into their respective ports until the connector tangs engage fully. Give a slight tug backward to ensure that the connector plugs are fully engaged.
  9. Slide the air inlet hose over the SCC neck and tighten the clamp until snug.
  11. Install the battery and connect the battery cables.
